Put off date — notice children around (8)
I believe the answer is:
dissuade
'put off' is the definition.
(I know that put off can be written as dissuade)
'date notice children around' is the wordplay.
'date' becomes 'd' (common abbreviation eg in DOB, date of birth).
'notice' becomes 'ad' (both can mean an advertisement).
'children' becomes 'issue' (issue can mean someone's offspring).
'around' indicates putting letters inside.
'ad' put into 'issue' is 'issuade'.
'd'+'issuade'='DISSUADE'
(Other definitions for dissuade that I've seen before include "Advise not to proceed" , "Discourage from course of action" , "Put off" , "Deter by advice" , "Try to deter" .)
